 For both option:--timer and option:--size options, LTTng checks the
 schedule condition periodically using the monitor timers of the tracing
-session's channels. This means that, with the option:--timer option, the
-automatic rotation can occur when the elapsed time since the last
-automatic rotation is greater than 'PERIOD', and with the option:--size
-option, the automatic rotation can occur when the size of the flushed
-part of the current trace chunk is greater than 'SIZE'. Therefore the
-'PERIOD' and 'SIZE' arguments are approximations. See the

 You can combine the option:--timer and option:--size options.
